BitDefender 2010 appears to have released a set of bad definitions. Unfortunately, these bad virus definitions appear to detect core DLL files and even parts of BitDefender.
We heavily recommend that you disable auto-update of the definitions until corrected ones are released.

There is quite a thread discussing this issue on the BitDefender Forums (http://forum.bitdefender.com/index.php?showtopic=18759&st=0).

Due to a recent update it is possible that BitDefender detects several Windows and BitDefender files as infected with Trojan.FakeAlert.5 .
In order to solve this issue you will have to perform these steps:

- open the BitDefender interface in Expert Mode
- go to the Antivirus tab and disable the Realtime Protection permanently.
- go to the Quarantine tab and restore all items that are detected as Trojan.FakeAlert.5.
- reboot your PC
- open BitDefender in Expert Mode
- go to the Update tab and run an update.
- wait for the update to finish and enable the Realtime Protection that was disabled earlier.

If, however, your Windows can no longer boot properly you will need to perform one of the 2 actions below:

1. Use Last Known Good Configuration
- reboot your PC and press F8 repeatedly until you reach a text menu
- choose the last option on the bottom of the page named Last Known Good Configuration

2. Use System Restore
